Mead, Queens Village, N. Y.,assignor to Mergenthaler Linotype Company, a corporation of New YorkThis invention relates to typographical machines, such as linotypemachines of the general organization represented in Letters Patent ofthe United States No. 436,532 to O. Mergenthaler, wherein circulatingmatrices are released from a magazine in the order in which theircharacters are to appear in print and then assembled in line, thecomposed line transferred to the face of the mold, the mold filled withmolten metal to form a slug or linotype against the matrices whichproduce the type characters thereon, and the matrices thereafterelevated and returned through distributing mechanism to the magazinefrom which they started.

More particularly, the present improvements deal with devices forremoving a matrix magazine from its base frame when it is desired toreplace such magazine with one containing a different matrix font. Inthe present instance, the base frame is equipped with devices normallyretracted within the frame but which are adapted, upon the removal of amagazine, to be extended to a position wherein they will support themagazine in a. vertical position in front of the machine clear of theframe, assembler throat, and other magazines should there be any. Thesemagazine removal devices are confined to the limits of the base frameand are moved from retracted to extended position and returnedautomatically during the removal and replacement of the magazine, suchmovement throughout being entirely within the plane of the base frame.

The invention is particularly advantageous when used with machinesemploying a plurality of matrix magazines in bank, since in such casesit is unnecessary to touch or disturb any of the magazines other thanthat which it is desired to replace. Although the improvements have beenillustrated in connection with a three magazine machine for the reasonsjust stated, it is apparent that they could be used with equal facilityin machines employing a greater or a lesser number. It may also be addedthat the magazines shown herein are socalled main magazines althoughthey could as well be auxiliary magazines.

Fig. 9 is a vertical section on line 9-9 of Fig. 8.

In the different embodiments, the matrices are stored according to fontor otherwise in the magazines A, three of which are shown, but of whicha greater or lesser number might be employed if desired. The severalmagazines are removably mounted upon separate base frames B, as by meansof lips or shoulders B rising from the forward or lower ends of the baseframes and engaging in front of cross ribs or plates A attached to theundersides of the magazines. The three base frames B are all connectedby means of screws B to a pair of side plates C, these parts thusconstituting a rigid shift frame for the magazines. The shift frame isin turn mounted in a relatively fixed supporting frame D pivoted at itsupper end (see Fig. 7) as at D to the machine frame and resting looselyat its lower end upon adjustingscrews (not shown) carried by the machineframe.

It may be stated here that themagazines here in shown are of the shortvariety and, for this reason there is employed in connectionwith themagazines, a channeled y.conductor E which serves to connect the activeone thereof with the customary magazine entrance F leading from thedistributing mechanism G. 'As will be noted from Fig. 7, both themagazine entrance F and Cil the channeled conductor E are mounteddirectly on the supporting frame.

In the embodiments illustrated, the magazines are each provided with afixed bank of escapements H adapted to be actuated in the usual way fromthe main keyboard but, as these parts are well known and form no part ofthe present invention, any further description would be superfluous. Ifdesired, reference may be had to the Kennedy Patent No. 1,561,244 forfuller information with respect to the keyboard connections. Anassembler entrance I is arranged to receive the matrices as they arereleased from the magazines and carry them to the composing orassembling mechanism.

In selecting one or another of the magazines for use, the shift frame Cis raised and lowered Within the fixed supporting frame D to bring theselected magazine into registration with the assembler entrance I at thefront and the channeled conductor E at the back.

The mechanism for raising and lowering the magazine shift frame (seeFigs. 1, 4 and 7) consists in part of a pair of cams J (only one ofwhich is shown) arranged at opposite sides of the machine and mounted ona shaft J extending horizontally beneath the magazines and journalled atits opposite ends in the supporting frame D. As the cams J are rotated,they cooperate with a corresponding pair of rollers J carried by theshift frame C to raise or lower the latter into a position wherein theselected magazine will be operative, the shift frame during theadjustment just mentioned being guided by anti-friction rollers J withwhich the sup porting frame D is equipped.

When it is desired to remove or replace a mag azine, the entiresupporting f ame D is rocked about its pivot D to raise the magazines toa position wherein the one selected for removal will clear the assemblerentrance I.

The mechanism for raising the supporting frame D includes a toggledevice consisting of a pair of pivotally connected members K and K themember K being rotatably connected to the cross shaft J and the member Kfastened to a rock shaft K journalled in the main frame of the machine,the arrangement being such that, as the rock shaft i is turned tostraighten out the toggle members, the supporting frame D will be raisedto its uppermost position wherein the removal of the magazines can beeffected. The rock shaft K is operated by a crank handle K arranged atthe side of the machine through two arms K and K and an interconnectinglink K the arm K being fixed to the crank handle, and the arm K fixed tothe rock shaft K and the intermediate link K being pivotally connectedat its opposite ends to said arms. If desired, the pivotally mountedsupporting frame D may be counter-balanced by a tension spring D (Fig.7) anchored at one end to the machine frame or a bracket carriedthereby, and connected at its opposite end to the rear arm of a lever Dpivotally mounted adjacent its center, and having a front arm providedwith an anti-friction roller D bearing against the frame D at thebottom.

The parts, as thus far described, are known constitute no part of thepresent improvements. For a more detailed description thereof, referencemay be had to the Burt Patent No. 1,864,799.

In order to remove a magazine from a machine equipped with theimprovements illustrated in Figs. 1, 2 and 3, the magazine supportingframe D is first raised to position the magazine selected for removalabove or clear of the assembler entrance I. The supporting frame D inits raised position is illustrated in Fig. 1, and there it will beobserved that the topmost magazine (which, for the setting of the cam Jas shown, would in its normal position register with the assemblerentrance I) has been elevated to clear the assembler entrance, so thatthe magazine may readily be removed in a forward direction. The magazineis then lifted slightly until the cross rib A clears the shoulders B onthe associated base frame B, whereupon the magazine may be slidforwardly in its own plane until another cross rib A fixed to theunderside of the magazine and rearwardly of the center of gravitythereof. engages a cross piece L secured at the front end of a pair oftelescoping slides L L carried by the base frame B. As the magazine isdrawn forwardly, the slides L and L will be extended as shown in Fig. 2,and, as the magazine leaves its base frame B, it thereafter will receiveits sole support from the slides which, when fully extended, willposition the cross piece L so that the magazine supported thereby can beswung into a vertical position (see Fig. 1) clear of the assemblerentrance I and likewise clear of the remaining magazines in the bank(this whether the magazine be the top one or a lower one).

In its vertical position, the magazine A. is held on the cross piece bya pair of brackets A riveted at their centers to the cross rib A and attheir rear ends to a similar cross rib A likewise fastened to theunderside of the magazine at the rear edge thereof. The brackets A(which in the retracted position of the slides are housed in recesses Bformed in the supporting frame B) have forwardly extending portions thatpass under the cross piece L as the magazine is drawn from its baseframe. The brackets A are spaced apart so as to engage the cross piece Lat its ends I which are partly cut away for clearance, and rounded offto facilitate rotating the magazine to its vertical position. Therounded portions extend inwardly from the outer ends of the cross pieceand terminate at the body portion proper of the slide L and also projectsomewhat above the upper face of the slide to present abutments againstwhich the cross rib A on the magazine engages to effect the extension01. the slides as previously described.

When the magazine is hanging on the cross piece L in its verticalposition, it is a simple matter to remove it and substitute anothermagazine for replacement in the machine.

The top telescoping slide member L (see Figs. 1 and 2) is slidablyarranged in the bottom slide member L which in turn is slidably arrangedin the base frame B at the center thereof. The top slide L at itslateral edges, is secured to the bottom slide L by tongue and grooveconnections L and the bottom slide L at its. lateral edges, is likewisesecured in the base frame by similar tongue and groove connections L thegrooves in the base frame being formed in part by a pair of plates Lscrewed to the frame and which overlie the tongue portions formed on thebottom slide. The slide L is formed in its upper face with afore-and-aft recess L centrally located and arranged to receive a rib Aattached at the underside of the magazine to the cross ribs A A and Afor guiding the magazine in its movement with respect to the slide; anddirectly beneath said recess, the slide is further formed in its bottomface With a boss L to satisfy strength requirements and which seats in acomplementary recess L formed in the upper face of the slide L The slideL and the base frame B are respectively formed with a similar boss L andrecess B for the same purpose.

The fore-and-aft movement of the top slide L with respect to the bottomslide L and of the bottom slide with respect to the frame B is limitedby two sets of gibs Z and Z the set Z being fastened to the bottom slideL and extending into a pair of recesses 1 formed in the opposite edgesof the slide L and terminating short of the ends thereof so as topresent shoulders which bank against the gibs, and the other set I beingfastened to the plates L on the base frame and extending into a similarpair of recesses Z formed in the opposite edges of the bottom slide Land which likewise terminate short of the ends of the slide L to presentshoulders cooperating with the gibs Z for the same purpose.

It might be stated here that the portion of the base frame presentingthe bearing surface for the bottom slide L is formed in two parts, therear part being integral with the frame proper and the front part beingconstituted by a plate B secured to the frame at the bottom in recessesprovided for the purpose and extending beyond the front edge of theframe so as to give additional support to the sliding members L and L Inorder to replace a magazine, it is first hung upon the cross piece L bymeans of the brackets A and thereafter tilted about the cross piece intothe plane of its base frame. The magazine is then pushed rearwardlyuntil the cross piece A thereon seats behind the shoulders B formed onthe base frame.

During the rearward movement of the magazine, the cross piece L remainsin its magazine supporting position until the magazine at its rear edgerests upon the base frame, whereupon a pair of angular-shaped brackets Asecured to a cross rib A on the underside of the magazine, will engagethe cross piece L and cause the retraction of the slides L and L withinthe base frame as the magazine is pushed home to its proper position onthe base frame. When the magazine is in its proper position, theangular-shaped brackets A just referred to, project into recess-es Bformed in the bottom face of the plate B such recesses having sufficientdepth to provide the necessary clearance for the brackets when themagazine is raised to clear the shoulders 13 at the front of thesupporting frame.

The telescoping slides L and L are held yield ingly in normal positionwithin the base frame B by two pairs of leaf springs Z and Z the pair 1being screwed to the base frame and adapted to engage in notches Zformed at the front edge of the bottom slide member L and the other pairZ being screwed to the bottom slide member and adapted to engage innotches Z formed in the bottom face of the top slide member L (see Figs.1 and 2). It will be noted that both the base frame and the bottom slidemember, directly beneath the leaf springs, are recessed as at Z so as toprovide clearance for the latter during the forward and return movementof the slides.

In the second embodiment illustrated in Figs. 4 to 6, the devices forsupporting the magazine in its forward vertical position, instead ofbeing telescopic, comprise a pair of angular-shaped pivoted member M Mmovable in the plane of the base frame B.

The members M, M are pivoted one at each side of the base frame on hingelugs M formed as an integral part of the end sections, as well as themain body portion of the frame, the lugs being somewhat thicker than thebody portion in order to provide the necessary strength. The members Mand M are formed with short rear arms m which bear against the undersideof the base frame, and longer front arms m which extend inwardly andcross each other at the center of the base frame, the arm of theleft-hand mem ber M being offset so as to clear the corresponding arm ofthe right-hand member M The bearing surface presented by the frame andthe large hinge lugs to the members M and M is further augmented byplates m riveted one to each of the arms m adjacent the hinge lugs andwhich have portions bearing on the top face of said lugs, segmentalportions of which are cut away to provide clearance. The arms m arefurther provided at their front extremities with members m riveted tothe arms and which present upstanding lugs m terminating just below theunderside of the matrix magazine.

Now in order to remove a magazine from the base frame, it is firstraised slightly to permit the cross rib A on the underside thereof toclear the shoulders B on the base frame, whereupon the magazine mayslide forwardly as in the embodiment previously described. As it does soand prior to the time that it leaves the base frame, a pair of plates Afastened to a cross rib A on the magazine will engage the lugs m andcause the members M and M to swing in the plane of the base frame fromthe position shown by the solid lines in Fig. 5 to the position shown bythe broken lines therein, in which latter position the magazine will besupported solely by said members. In the extended position of themembers M and M the magazine (even though it be a lower one) will clearthe other magazines in the bank and can be rotated into the verticalposition shown in Fig. 4, where it is sustained by the engagement of theplates A with the lugs m. In this position, the magazine may be readilyremoved and a different one substituted therefor.

The extended positions of the members M and M are determined by a pin mwhich passes through slots m formed in said members and havingsufiicient length to permit free movement of the members M and M betweentheir retracted and extended positions. Furthermore, the pin m isprovided at its opposite ends with heads m that engage the top andbottom faces of the members M and M respectively and serve to hold themtogether so as to act as a unit in supporting the magazine. In theretracted position of the supporting members, the pin will restrearwardly of the front edge of the base frame, the center rib of whichis recessed as at m to give the necessary clearance (see Fig. 5).

It may be noted that the plates A project for a short distance forwardlyof the cross rib A and, due to the thickness of the latter, the extendedportions will be spaced somewhat from the un derside of the magazine,thereb permitting the lugs m on the arms m to engage behind the platesso as securely to support the magazine when in its vertical position.Furthermore, the plates A are of suiiicient length to insure engagementwith the lugs m throughout the movement of the arms m from their normalretracted position to their fully extended position.

In order to replace a magazine on the base frame, it is first placed ina vertical position on the members M and M then tilted into the plane ofthe base frame, and thereafter pushed rear- (iii wardly, the membersremaining in their extended position until after the rear edge of themagazine has passed beyond the front edge of the frame for a shortdistance, whereupon another cross rib A secured at the underside of themagazine will engage the lugs m on the members and swing them back totheir normal retracted positions within the frame.

The magazine is guided in its movement on the base frame by afore-and-aft bar A (Figs. 5 and 6) riveted to the magazine cross ribsand which slides in a guid'eway formed in the center rib of the baseframe.

The third embodiment illustrated in Figs. '7, 8 and 9 is similar to thatshown in Figs. 4, 5 and 6, in that there are provided two members N andN pivotally mounted adjacent the lateral edges of the base frame andmovable in the plane thereof from a retracted position within the frameto an extended position out of the frame where the magazine is supportedin a vertical position clear of the assembler throat and the othermagazines in the bank. In this instance, however, the members N and Nare formed with arm portions n and n meeting at the center of the baseframe when the members are in their normal or retracted positions, andare also formed at their inner ends with arcuate portions n and 11.extending to the rear edge of the base frame and provided in theiradjacent edges with complementary gear teeth 11 which cause the membersN and N to move in unison. The members N and N have a bearing on thebody portion proper of the base frame, winch for this purpose is formedwith arcuate ribs B corresponding to the arcuate portions 11 n of themembers, and said members are held slidably against the bearing surfacesby anti-friction rollers 11 mounted on pins n fixed in the base of theframe, the rollers seating in recesses n formed in the edges of thearcuate portions 11 n opposite the edges that present the teeth (Figs. 8and 9).

When the members N and N are in their retracted position, the rear edgesof the arm portions 11., n thereof bank against the rollers n whereaswhen they are in their extended position, lugs 11, formed at the outerends of the arcuate portions 12 and n bank against the pins 11 it beingin this manner that the retracted and extended positions of the membersare determined.

The magazine on its underside and at the rear edge is provided with across rib A extending the full width of the magazine, and at a shortdistance forward of said rib there is also provided another cross rib Ato which latter there are secured two plates A presenting overhangingportions for a purpose presently to be described. The magazine furtheris equipped with a center bar A fastened to both cross pieces A and Aand extending toward the front of the magazine somewhat beyond the frontedge of plates A just alluded to.

In order to remove a magazine from the base frame, it is lifted to clearthe shoulders B formed thereon, as in the embodiments previouslydescribed, and allowed to slide forwardly, and short ly after it startsits forward movement, the center bar A at its front end will engage apair of shoulders 11 formed one on each of the arcuate portions n and nin the edges thereof that carry the teeth. As the magazine continues inits movement, said center bar will rotate the members N and N from theposition shown by the solid lines in Fig. 8 to that shown by the dottedlines therein, which is just about half the full range of theirmovement. The magazine will now move a small distance by itself, butshortly thereafter the plates A will engage a pair of lugs 11. formedone at each of the inner ends of the straight arm portions n, n of themembers N and N and, as the magazine continues to move forwardly, saidplates will effect the movement of said members to the position shown bythe broken lines in Fig. 8. In this final position, the members arefully extended and the magazine can be .Swung to a vertical position infront of the assembler throat, the lugs 12 engaging behind the plates Ato hold the magazine suspended. With the magazine suspended in thismanner, it is a simple matter to remove it and replace it by anothercontaining a different font.

In order to replace a magazine on the base frame, it is first suspendedin a vertical position on the members N and N then tilted into the planeof the base frame, and thereafter pushed rearwardly, the membersremaining in their extended position until after the rear edge of themagazine has passed beyond the front edge of the supporting frame,whereupon the cross rib A on the underside of the magazine will engagethe lugs n and return the members to their normal retracted positionwithin the base frame. Since the lugs n in the retracted position of themembers N and N stand to the rear of the shoulders E the cross rib A inthis instance is made wider in its center region in order that themembers will have been returned fully to their normal position when thecross rib A engages behind the shoulders B on the base frame.

It may be stated that the shoulders 72*, against which the center bar Abanks to eifect the first part of the extending movement of the membersN and N are presented at the front ends of a pair of recesses n formedin the opposed edges of the arcuate portions 11 and n just above theteeth a and which are present to provide clearance for the center barduring its movement.

It will be noted, as to each of the three different embodiments shown.and described, that the operation of the magazine removal devices isentirely automatic, the operator in removing a magazine from its baseframe proceeding as if the removal devices were not present. Thus, inremoving a magazine, the operator grasps the magazine at its lower endand, after disengaging it from the stop shoulders on the base frame,slides it straight forwardly along the base frame. just as he does inexisting machines, paying no attention whatever to the magazine removaldevices Which, as a matter of fact, are inaccessible and entirelyconcealed from view. The first or initial movement of the magazine isentirely free and of considerable extent, but thereafter the magazinepicks up the removal devices and pulls them out of the frame to theirextended position, the magazine being supported by the base framethroughout its whole sliding movement until just near the end of suchmovement, when the rear end of the magazine passes beyond the lower orforward end of the base frame; at this time, the removal devices haveassumed their fully extended position and no further sliding movement ofthe magazine is permitted, so that the magazine is then allowed toassume its vertical position in front of the assembled entrance where itcan be handled with ease. Similarly, in replacing the magazine upon thebase frame, the magazine is first tilted from its vertical position backinto its normal inclined position .and then slid straight-rearwardlyuntil it assumes its proper position on the base frame. Here again, thefirst or initial part of this rearward movement of the magazine is freeor relative to the magazine removal devices, these devices being pickedup by the magazine in its continued rearward movement and restored totheir normal or retracted position within the base frame by the finalpart of such movement. This differential movement of the magazine andits removal devices aids in keeping these devices confined wholly withinthe limits of the base frame, which is an important feature andespecially in a movable multiple magazine machine, such as shown,wherein the base frames must be moved upwardly and downwardly withreference to contiguous parts to bring any selected magazine intooperative position. In this connection, it will be understood of coursethat, in each of the embodiments illustrated, all the base frames willbe equipped with magazine removal devices, the description givenapplying to them all and not being limited to one frame only.

In the accompanying drawings the invention has been shown merely by wayof example and in preferred form, and obviously, many variations andmodifications may be made therein which will still be comprised withinits spirit. It is to be understood, therefore, that the invention is notlimited to any specific form or embodiment, except insofar as suchlimitations are specified in the appended claims.
